[0057] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0058] In one embodiment, such as Figure 1 As shown, a time calibration method for a dynamic token is provided. Taking the application of this method to a control device (i.e., the control unit of the dynamic token) as an example, the method includes the following steps S101 to S104:

[0059] Step S101: If the triggering conditions for the time calibration mode for the dynamic token are met, then enter the time calibration mode.

[0060] In this application, the dynamic token serves as a security device for authentication. The control unit detects different operations performed on the operation keys included with the dynamic token to determine whether the triggering conditions for the dynamic token's time calibration mode are met. If so, the dynamic token enters the time calibration mode. In this mode, calibration parameters are calibrated to obtain the target's internal time factor, which is then used to generate a new dynamic password. Only one operation key is used in this mode.

[0061] Step S102: Determine the calibration range based on the calibration coefficient.

[0062] In applications, the calibration coefficient represents the number of steps that the dynamic token can calibrate forward or backward per working cycle. The unit of the working cycle can be year, month, day, etc. The number of steps can refer to N (N is a positive integer) hours, minutes, seconds, etc. For example, if the working cycle is in years, the maximum forward calibration step per year is 1 minute. The calibration coefficient is a positive integer, and in applications, the calibration coefficient can be set according to the characteristics of the dynamic token, the usage scenario, etc., and is usually between 5 and 20. When the control unit performs time calibration, in order to improve calibration efficiency, it usually sets a calibration range to perform time calibration within the calibration range, thus achieving rapid calibration. The calibration range can be determined directly based on the calibration coefficient, or it can be determined jointly based on the calibration coefficient and the working cycle of the dynamic token.

[0063] Step S103: Based on the specified operation for the operation key, adjust the calibration parameters within the calibration range.

[0064] The calibration parameter refers to the error or deviation between the internal time factor to be calibrated and the internal time of the dynamic token. Time errors are reduced by dynamically adjusting the calibration parameter within the calibration range. In application, in time calibration mode, the control unit receives a specified operation for the operation key, allowing adjustment of the calibration parameter within the calibration range until a time confirmation command is received, at which point the adjustment pauses.

[0065] Step S104: Based on the adjusted calibration parameters and internal time, determine the target internal time factor, which is used to generate the dynamic password.

[0066] In this application, the internal time is the real-time time of the internal clock based on the dynamic token. The sum of the adjusted calibration parameters and the internal time is used as the target internal time factor. This target internal time factor can be used to generate dynamic passwords.

[0067] In this embodiment, a time calibration mode is triggered by a single operation key. Within this mode, a calibration range is determined based on a calibration coefficient. Combined with a specified operation on the operation key, calibration parameters are adjusted within this range. Finally, based on the adjusted calibration parameters and the internal time, a target internal time factor is obtained, and a new dynamic password is generated based on this target internal time factor. Thus, while ensuring the security of the dynamic token, accurate internal time calibration can be completed with a single operation key, which is not only convenient but also enhances the human-computer interaction experience.

[0068] In one embodiment, such as Figure 2 As shown, the implementation process of step S102 includes the following steps S201 to S202:

[0069] Step S201: Determine the limit range based on the calibration coefficient.

[0070] In application, the limit range is used to restrict the maximum adjustable range of the calibration parameters. The calibration parameters are adjusted within this limit range. The limit range can be determined based on the working cycle of the dynamic token. If the working cycle is greater than zero, the working cycle is rounded up to obtain the integer result. The positive form of the product of the integer result and the calibration coefficient is used as the upper limit of the limit range, and the negative form of the product is used as the lower limit of the limit range. The range [negative form of the product, positive form of the product] is the limit range. It should be noted that if the working cycle is zero, the range [negative form of the calibration coefficient, positive form of the calibration coefficient] is directly used as the limit range.

[0071] Step S202: Determine the calibration range based on the limit range, calibration parameters, and calibration amplitude.

[0072] In application, the control unit determines the calibration range based on the limiting range, calibration parameters, and calibration amplitude. Specifically, a temporary limiting range for the calibration parameter is first determined based on the calibration amplitude, and then the intersection of the temporary limiting range and the actual limiting range is used as the calibration parameter. Let the calibration parameter be T, the calibration amplitude be m, and the calibration coefficient for the temporary limiting range [Tm, T+m] determined based on the calibration amplitude be k. Then the limiting range is [-k, k]. The intersection of [Tm, T+m] and [-k, k] is then used as the calibration range.

[0073] In this embodiment, the method of determining the calibration range by combining calibration coefficients, calibration parameters, and calibration amplitude can improve the accuracy of determining the calibration range.

[0074] In one embodiment, such as Figure 3 As shown, the implementation process of step S201 includes the following steps S301 to S302:

[0075] Step S301: Round up the working period of the dynamic token to obtain the rounded result.

[0076] In applications, if the rounding result of the working period of the dynamic token is positive, the calibration range can be determined by combining the working period of the dynamic token.

[0077] Step S302: Determine the product of the rounding result and the calibration coefficient to obtain the time adjustment threshold denoted as k, where k is a positive number. Determine the set of integers in the range [-k, k] as the restriction range, where the calibration coefficient is a positive integer.

[0078] In application, the process of determining the calibration range by combining the working cycle, calibration coefficient, and internal time is as follows: First, the rounded result and calibration coefficient are used to determine the time adjustment threshold, denoted as k, the working cycle as y, and the calibration coefficient as x. The range is limited to integers between [-k, k], that is... Integers between [a certain range].

[0079] For example, if the working time of the dynamic token device is 2.5 years and the calibration coefficient x is 5 minutes, then rounding up the working period of 2.5 years gives 3, and the resulting time adjustment threshold is 3 × 5 = 15. The step size is in minutes, which means 15 minutes. The corresponding limit range is [-15, 15].

[0080] This embodiment obtains the time adjustment threshold by rounding up the working time of the dynamic token and multiplying the rounded result by the calibration coefficient, which can accurately calculate the allowable time calibration range of the dynamic token in different working cycles.

[0081] In one embodiment, the triggering condition for the time calibration mode of the dynamic token in step S101 includes at least one of the following: the pressing duration of the operation key reaches a preset duration threshold; or the number of consecutive clicks on the operation key within a specified time reaches a preset number threshold.

[0082] In application, the control unit triggers the time calibration mode for the dynamic token by performing different operations on a single key included in the dynamic token device. That is, the triggering condition for the time calibration mode is determined based on the different operations of the key.

[0083] In the application, the triggering condition for the time calibration mode of the dynamic token can be that the pressing duration of the operation key reaches a preset duration threshold, or that the number of consecutive clicks on the operation key reaches a preset number threshold within a specified time.

[0084] For example, pressing the operation key of the dynamic token device for more than a preset duration threshold (2 to 5 seconds) or pressing the key multiple times in a short period of time (such as double-clicking) will enter the time calibration mode.

[0085] This embodiment allows for easy entry into time calibration mode through simple physical operations, improving operational convenience and user experience. It also ensures that the dynamic token can be calibrated in a timely manner, reducing time deviation and enhancing the accuracy and security of identity verification.

[0086] In one embodiment, the specified action includes a long press action, such as... Figure 4 As shown, the implementation process of step S102 includes steps S401 to S402:

[0087] Step S401: Determine the adjustment step size based on the adjustment method, which may include adjusting by second or by minute.

[0088] In the application, the adjustment step size is determined according to the preset adjustment method, which includes adjustment by second and adjustment by minute. If the adjustment is by second, the adjustment step size is 1 second; if the adjustment is by minute, the adjustment step size is 1 minute.

[0089] In step S402, in response to a long press operation on the operation key, if the press duration of the long press operation reaches the first duration, the calibration parameters are continuously adjusted within the calibration range based on the adjustment step size, with the second duration as the adjustment interval.

[0090] In application, internal time calibration can be achieved by long-pressing an operation key. When the control unit receives a long-press operation, if the press duration reaches a preset first duration, it continuously adjusts the calibration parameters within the calibration range, combining the adjustment interval and adjustment step size, until a time confirmation command is received. The adjusted calibration parameters at this point are then used as the target calibration parameters. The adjustment interval refers to the time between two changes in the internal time factor. The duration corresponding to the adjustment interval is the second duration.

[0091] For example, if the adjustment interval is set to a range of 100 milliseconds to 1000 seconds and the adjustment interval is set to 500 milliseconds, then during the long press, the internal time factor will increase by one adjustment step every 500 milliseconds. If the adjusted internal time factor reaches the upper limit of the calibration range, then after another 500 milliseconds, the internal time factor will be adjusted to the lower limit of the calibration range, and the adjustment will start from the lower limit and gradually continue until the target internal time factor is obtained.

[0092] For example, assuming the dynamic token has been working for 2.5 years, the calibration factor x is 5 minutes, and the internal time is 14:30:00, if the user presses and holds the operation button for 3 seconds, the dynamic token enters time calibration mode, with a calibration range of 14:30:00 ± 15 minutes, i.e., 14:15:00 to 14:45:00. The dynamic token displays the current time as 14:30:00. If the user continues to hold the button, the time information cycles through the time in minute increments: 14:31:00, 14:32:00, ..., etc.

[0093] In this embodiment, the internal time can be calibrated simply by long-pressing the operation key, which simplifies the operation and enables cyclic traversal within the calibration range.

[0094] In one embodiment, during the execution of step 302, the following functions can also be implemented: upon receiving an end command for a long press operation, pause the adjustment of calibration parameters; simultaneously, in response to a click operation on the operation key, generate a calibration confirmation command; and based on the calibration confirmation command, control the exit from the time calibration mode.

[0095] In the application, when the user holds down the operation key, the calibration parameters are continuously adjusted within the calibration range. When the user sees that the displayed time matches the current time, they release the key. At this point, the dynamic token detects the key release and receives an end command for the long press operation, thus pausing the adjustment of calibration parameters. When the user clicks the operation key again, a calibration confirmation command is generated, indicating confirmation of calibration, the adjusted calibration parameters are obtained, and the user exits the time calibration mode.

[0096] This embodiment provides a clear confirmation mechanism to ensure that users can easily end the calibration process after adjustment, improving the convenience of operation and user experience, while ensuring the accuracy of the internal time of the dynamic token and the security of identity verification.

[0097] In one embodiment, the calibration parameters can also be adjusted through other specified operations on the operation keys. After entering the time calibration mode, in response to a single click operation on the operation key, the calibration parameters are controlled to increase by one adjustment step; in response to a double click operation on the operation key, the calibration parameters are controlled to decrease by one adjustment step.

[0098] In application, during calibration, the control unit responds to a single click of the operation key by increasing the internal time by one adjustment step. The adjustment step size is adapted to the adjustment method: if the adjustment method is in minutes, the step size is 1 minute; if the adjustment method is in seconds, the step size is 1 second. A double click of the operation key decreases the internal time by one adjustment step.

[0099] It should be noted that a single-click operation can be set to decrease the internal time by one adjustment step, and a double-click operation can be set to increase the internal time by one adjustment step. This embodiment does not limit the specific correspondence.

[0100] This embodiment provides a flexible and intuitive time adjustment method, allowing users to easily fine-tune the internal time within the calibration range to ensure that the internal time of the dynamic token is synchronized with the server time, thereby improving the accuracy of dynamic password generation and the security of authentication.

[0101] In one embodiment, the dynamic token further includes a display screen, which performs the following functions: based on a preset display mode, during the adjustment process, it displays the change process of the real-time internal time factor, wherein the real-time internal time factor is determined by the first internal time and the real-time calibration parameters during the adjustment process.

[0102] In the application, the real-time internal time factor change process can be displayed during adjustment using a preset display mode. The display mode is related to the adjustment mode, which can be adjusted by seconds or minutes. If the adjustment mode is by seconds, the real-time internal time factor is displayed as a 6-digit number in hour, minute, and second format, such as 14:30:15. If the adjustment mode is by minutes, the real-time internal time factor is displayed as a 4-digit number in hour and minute format, such as 14:30. The first internal time can be the internal time when entering time calibration mode, or it can be the real-time time based on the internal clock.

[0103] This embodiment allows users to intuitively see the progress of time adjustment, ensuring the transparency and accuracy of the adjustment process, and improving the convenience of operation and user experience.

[0104] This application also provides a dynamic token time calibration device for performing the steps in the above-described dynamic token time calibration method embodiments. For example...

[0107] Adjustment module 530 is used to adjust calibration parameters within the calibration range based on a specified operation for the operation key.

[0108] The second determining module 540 is used to determine the target internal time factor based on the adjusted calibration parameters and internal time. The target internal time factor is used to generate a new dynamic password that is synchronized with the server time.

[0112] In one embodiment, the triggering condition for the time calibration mode of the dynamic token includes at least one of the following: the duration of pressing the operation key reaches a preset duration threshold; the number of consecutive clicks on the operation key reaches a preset number threshold within a specified time.

[0113] In one embodiment, the specified operation includes a long press operation. The calibration module is also used to determine the adjustment step size based on the adjustment method, which includes adjustment by second or adjustment by minute. In response to a long press operation on the operation key, if the press duration of the long press operation reaches a first duration, the calibration parameters are continuously adjusted within the calibration range based on the adjustment step size, with a second duration as the adjustment interval.

[0114] In one embodiment, the calibration module is further configured to pause adjusting calibration parameters if an end command is received for a long press operation; generate a calibration confirmation command in response to a click operation on an operation key; and control the exit from the time calibration mode based on the calibration confirmation command.

[0115] In one embodiment, the calibration module is further configured to display the change process of the real-time internal time during the adjustment process based on a preset display method, wherein the real-time internal time factor is determined by the first internal time and the real-time calibration parameters during the adjustment process.
